Google is handing you the mixing board for Gemini’s voice
For months, Google has been quietly pushing Gemini to sound less like a robot reading a script and more like, well, a person. The next step? Letting you dial in exactly how that person talks.
Fresh code pulled from the latest Google app beta (version 17.41.12) points to a new Gemini voice customization panel. Instead of picking from a handful of preset personalities, you’d get four separate sliders: Energy, Formality, Warmth, and Speed. Each one runs from Low to High (or Slow to Fast for speed).
That’s a meaningful departure from the current setup, where your choices are essentially limited to the voices Google cooked up for you.
What the new controls actually do
The feature hasn’t been announced yet, so we’re working from what’s visible in the code. Android Authority’s APK Insights team dug into the strings and found a dedicated “Customize” section tucked inside Gemini’s voice settings.
Here’s the breakdown of what you’d be able to adjust:
- Energy: Low, Medium, High
- Formality: Low, Medium, High
- Warmth: Low, Medium, High
- Speed: Slow, Normal, Fast
These aren’t meant to replace the existing voices. Rather, they’d layer on top of them. So you could pick a voice you like and then tweak its delivery to match your mood or use case — say, a brisk, formal tone for work queries and a slower, warmer one for casual chats.
The settings are expected to carry across both Gemini Live and the standard chat interface, which means you won’t have to reconfigure things depending on where you’re talking.
Why this matters after the Google I/O refresh
This discovery lands right after Google overhauled the voice picker following I/O. The old carousel interface is gone, replaced with a cleaner list. Two new voices — Flare and Glow — joined the lineup, bumping out Nova and Lyra.
The current roster now stands at ten voices: Ursa, Vega, Pegasus, Dipper, Eclipse, Capella, Orbit, Orion, Flare, and Glow.
Interesting detail: Google also stripped away the personality labels that used to describe each voice, things like “Calm” or “Bright.” Now you’re left to judge purely by ear. That move makes more sense in hindsight — if users are about to get granular controls, the preset descriptions become less relevant.
The interface is getting a facelift too
Alongside the voice changes, the update refreshes Gemini’s icons — slimmer, more modern takes on the microphone, camera, gallery, file upload, video, screen sharing, and Gemini Live buttons. These visual tweaks are rolling out via a server-side update alongside Gemini version 1.0.913571982.
Google isn’t the only one tuning voices
This push toward personalization fits a broader trend. At Google I/O, the company said regional dialects are on the roadmap for Gemini. Voice customization slots neatly into that effort to make AI feel less generic.
Apple is heading the same direction. Apple‘s iOS 27 gives Siri AI similar controls — Pace and Expressivity — and those preferences extend across Maps and Safari.
The subtext here is clear: the AI race isn’t just about what assistants can do anymore. It’s about how they sound while doing it. Tone, warmth, and cadence are becoming competitive battlegrounds.
What to expect next
None of this is official yet. Code in a beta doesn’t guarantee a public rollout, and Google could tweak the feature before it ships. But the trajectory is obvious.
If this lands as expected, you’ll soon be able to shape Gemini’s voice to fit your ear — not the other way around. For anyone who’s ever winced at a too-chipper assistant or struggled to follow a machine-gun-fast response, that’s a genuinely useful upgrade.
